Good places for bird photography (in terms of hide locations)

[Zephyr]

Does anyone know of other good hides for bird photography? I know of quite a few hides, but only very few of them seem suited to bird photography - can anyone recommend any locations in particular which have nice perches and hides that are fairly good for bird photography if you get what i'm saying.
I live in Cornwall but anywhere in Cornwall / Devon / Somerset would be helpful

Thanks in advance
